This study presents new findings on the impact of strain-induced surface phase transformation on the alleviation of hydrogen embrittlement in an austenitic high Mn steel. The results obtained indicate that the strain-induced epsilon-martensite on the surface of the sample significantly reduces adsorbed hydrogen and elongation loss, which is attributed to the lower diffusivity of hydrogen in epsilon-martensite compared to austenite.
